Updates on some old favourites

Knockhardy Publishing, Chemguide, and Practical Chemistry are reviewed

Knockhardy Publishing

I recommend this site as the first stop for A-level chemistry teachers, especially for teachers new to AS/A2 teaching. Produced by Jonathan Hopton, the materials on the site have recently been updated to reflect a change of emphasis from the AQA specification to OCR, though you can still access the old AQA materials. The site provides access to a vast array of worksheets, notes, revision sheets and multiple-choice tests, along with some animations of mechanisms and other ideas lifted from the PowerPoint presentations. New for the 2008 OCR specification are notes on green chemistry, fuel cells, and errors and measurement.
